Mine just arrived today. I agree the buttons are mushy and it is quite hard to remove but the Cyan colour looks so good it does not creak at all. The plastic feels slightly lighter than the original but that's because it lacks the nfc and QI charging pad. I bought mine for just 2.73 btw.

I've glued the camera button permanently in place using plastic cement and a syringe because it doesn't spring back into its original position and messing up my camera focussing so I have to rely on the on-screen button from now on which I don't really mine. The power button is recessed too much for my liking but i can still press it using my nail. I'm wiling to sacrifice the buttons usability for now because I really like the colour. Also I'm pairing it ORZLY Fusion case which is an awesome case btw.
